The
Shortest Sentence in the English Language

The shortest English language sentence is not “I am.” Follow along now—it does get technical.

“I am,” first of all, is not a sentence. An English sentence must have a subject / predicate relationship, and the key element in that relationship is the type of verb that creates the predicate. Verbs either show action or they do not. Verbs without action, such as “am,” when used as a predicate, must have something to complete the meaning—a complement. So you “am” “something.” “I am happy” is a sentence since “happy” is fulfilling the complement role. Therefore, “I am” is not a sentence.

The shortest English sentence is probably “Go.” “Go” is an action verb and can be used in imperative mood, which means that it can be used with good, old “You Understood.” So “Go” actually means “You go.” On the other hand, if that interpretation doesn’t strike your fancy, let’s say that understood meanings are disallowed, then “I go” is the shortest sentence. “Go” doesn’t require a complement since it is an action verb nor does it require a direct object. With a total of three letters—the same number as the illegal “I am” contender—“I go” should reign as the champion, unless someone out there knows of a single letter verb. (No fair pulling in Old English and foreign languages.)
